Possibly, but would any of us been able to spot the possible wing mounted L-band radar on even the highest quality J20 pictures with full camouflage?

Who knows what other nuggets of detail and insight truly hi res primer shots might reveal, especially if they get to production stage and don't bother to cover everything in yellow primer before rolling the birds out of the shops.

The Chinese security services may well decide hi res primer shots don't reveal enough to warrant blanket banning, or they might. Which is the point. It's not a given that every leak will follow the normal trend because that trend developed for this precise reason.

Well yes, I was never suggesting that ever leak would ever follow the "normal" trend, only that I believe it could be reasonable for us to consider that they'd allow photographers to release HQ shots of J-20s in primer.

China Has Started Building the J-20 Stealth Fighter

This 5th-generation fighter is the country's first stealth jet.


China's Chengdu J-20 fighter has officially entered the early stages of production. The bird you see here is the first production model of the large, stealthy fighter, photographed on the tarmac just days ago. The fighter, marked 2101 on the fuselage, is painted a dull yellow—likely a primer coat.

The low rate initial production (LRIP) fighters will likely go to People's Liberation Army Air Force (PLAAF) test pilots for flight testing. The prototype's appearance means that most of the plane is likely frozen, design-wise, with no major changes anticipated. This new change of status puts the roughly at the same development level as the F-35 Joint Strike Fighter.



China developed the J-20 at a positively breakneck pace by the standard of bring a new warplane to bear. The aircraft first flew in January 2011, and by November 2015 the eighth prototype had been flown. By comparison, It took the U.S.—which actually had built a fifth generation fighter before—nearly two decades to develop the F-35.

The plane has enjoyed visible improvements along the way. Prototype 3 featured redesigned air intakes, a less rounded, more angular nose, and an electro-optical targeting system. Prototypes 5 and 6 featured sharper "strakes"—small winglets trailing the wings that mask the engine exhausts from radar.

This new change of status puts the roughly at the same development level as the F-35 Joint Strike Fighter.

One open question about the new fighters is whether they use Russian or Chinese engines. Prototypes of the J-20 used the Russian AL-31 "Saturn" engine, the same one that powers the Chinese Navy's J-15 "Flying Shark" carrier-based fighters. But China has poured resources into building its own modern high-performance engines, and ultimately the J-20 is expected to be powered by the locally produced WS-15. But while the J-20 has come along quickly, the engine is still not ready for primetime. Development of the WS-15 has dragged on for nearly 20 years, stymied by a lack of Chinese metallurgical experience.

As impressive as it may be that the J-20 is going into production, there are reasons to remain skeptical of this new stealth jet. China is very careful about the information that is released, so outside observers really know only what China wants us to know. There are a lot of unanswered questions. What radar will it use? Why have two aircraft never been sighted in the air together? Is this an air superiority fighter, a penetration bomber, or both?

We may find out that China has made design choices that would be unacceptable in an American fighter—or we may find out that the People's Republic has made something fully the equal of the best the America military-industrial complex can offer. The truth is probably somewhere in-between.

Is this really important that it says anything. I've brought it up in here simply because I'd like to see two J-20s up in the air in a single shot.

If Kyle Mizokami read this forum, he wouldn't write the drivel that he normally does. Maybe he just started; this piece is definitely best I've seen out of him.

If he is reading from here, he's obviously spinning it to fit his agenda.

Agreed, my point being the "edit" part leverages a lot of the hard work (image collection, prototype version changes and estimated J-20 capability analysis cited on SDF)... but there's some definite "freestyling" around the WS-15's 20 year development...

If I am not mistaken, the very best human pilot can withstand is 12g for only a few seconds, and 9g for a very short period or they will simply black-out. That's after years of very intensive training. Missiles on the other hand can go 20g+ regularly and more than 100g+ recorded for some older missiles.

Its really down to physiology and physics - as we found newer and stronger materials, couple with better and superior construction / manufacturing methods, and smarter and better A.I. for the CPU, better sensors - the missiles will in the near future out-maneuver human pilot every single time.

Super maneuverability will become a useless feature in the future combat aircraft.


Trends in Air-to-Air Combat: Implications for Future Air Superiority

Dodging missile does not equal to out-maneuver the missile. The biggest advantage of the aircraft is energy. An A2A missile can carry very limited fuel a.k.a very limited energy. The higher Gs the missile pulls, the faster it bleeds energy. Unlike fighters, missiles only have so much energy at disposal. No energy = no fancy tight truns = 20g or 50g or 1000g maneuverability become useless. Fighters only need to out-run (out energy) instead out-maneuver the missile to survive.

I must have missed the memo for that, since when did green wheels signify operational service, informally or otherwise?

Because I just checked the Chinese air force's combat aircraft just now and the only aircraft with green wheels are the Q-5 variants, J-7 variants, and flanker variants... And even then not every wheel is green, e.g. J-7s only have the forward wheel green while the aft ones are not, vice versa for flankers.
J-8 variants, JH-7 variants, J-10 variants, JF-17, on the other hand all never have been seen with green wheels either in service or in prototype stage, as far as I am aware.
J-20 doesn't have green wheels for its prototypes either so it is doubtful its wheel colour will somehow change once it enters service.

In other words, I believe there is no evident to say green wheels in Chinese air force fighters represents "operational service" because there are so many types of aircraft in service without green wheels. It would be more accurate to say a few types of aircraft on service (flankers, J-7s and Q-5s) have green wheels.
I also believe there is no evidence to suggest that wheel colour changes between prototypes and in service aircraft. I have not seen such a thing occur for previous aircraft projects and I have no reason to believe it will be the case for J-20.

Rumor basically started with Chinese Flankers (J-11 and J-15 especially) . Prototype variants had grey wheels, as they become operational they switched to green ones . J-20 is logical successor to Flanker family, so it is possible that same pattern will emerge . Of course, this is all highly speculative , but we are grasping at straws here do to the lack of real information ;)
